AI-Generated

The vulnerability affects the MegaMenu layout in the Helix Ultimate Joomla extension, where unsanitized configuration values can lead to stored Cross-Site Scripting (XSS) attacks. This allows attackers to inject malicious HTML or JavaScript, potentially compromising user data and site integrity. Joomla administrators and developers using versions prior to 2.2.10 should prioritize applying the latest updates to mitigate this risk.
